' Specification of Letters Patent.

Patented June 20, 1916..

Application filed January 27, 1914, Serial No. 814,679. Renewed November 11, 1915. Serial No. 60,994.

To all whom it may concern:

Beit known that 1, DAVID F. CURTIN, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have made certain new and use-- ful Improvements in Sanitary Paper Cups and Dishes, of which the following is a specification.

My invention is an improvement in sanitary paper cups and dishes, and has for its object to provide a cup or dish formed from a blank cut to shape and creased, and. afterward folded in a particular manner to form a receptacle for containing soda fountain products, and especially adapted for use in the soda cup holders and dishes forming the subject matter of my co-pending applications, Serial No. 799,705 and Serial No. 805,035.

In the drawings: Figure 1 is a perspective view of a form of cup, Fig. 2 is a plan view of the blank from which the cup shown in Fig. 1 is formed, Fig. 3 is a partial horizontal section of the holder forming the subject matter of my above-mentioned co-pending patent, showing the manner of holding the formed dish in position to hold ice cream or the like, Fig. 4 is a perspective view of a soda cup, and Fig. 5 is a plan View of the blank from which the cup shown in Fig. 4 is formed.

The embodiment of the invention shown in- Figs. 1 to 3 inclusive is formed from a paper blank 1 of approximately circular form but having a strip indicated at 2 removed 'from the blank at theperiphery thereof. The said strip 2 is bounded between two radii at an angle of 90 degrees.

with respect to each other, the periphery of the blank, and an are parallel with the periphery. Crease lines 3 are then formed in the blank leading from the center 4 thereof to the radial shoulders 5 which are formed by the removal of the strip 2 before mentioned. .The said lines 3 are radius lines, and coincide with the shoulders 5 before mentioned. A third crease line 6 is formed leading from the center 4: of the blank to a point halfway between the shoul-= ders 5, that is halfway between the radius lines3.

The dish is formed by bending the blank on the crease lines 3 and 6, that portion of the blank between the radius lines 3 being bent outward, and doubled upon itself, upon the radius lines 6. The radius line 6 is halfway between the radius lines 3, so that the portions 7 between each radius line 3 and the radius line 6 are of equal size. A flap shown in Figs. 1 and 3 is thus formed by the two portions 7, extending radially with respect to the dish, the remaining portion of the blank constituting a conical cup or dish, as shown.

The holder 8forming the subject matter of the above-mentioned application No.

805,035 has a slot extending from the center thereof to near the rim, and the opposite sides of the slot are ofi'set with respect to each other, as indicated at 9 and 10 in Fig.3. The flap formed by the folding of the portions 7 upon each other is passed through the slot, and the sides 9 and 10 point. 1

The rim of the holder is beaded over, and the free edge of the blank 1 is bent over the said bead, as shown at 11 in Fig. 1,

of' the slot clamp upon the flap, to hold it in place, and to prevent leakage at this in Figs. 1 and 5 is more especially designed for use with the soda cup holder forming the subject matter of my above-mentioned co-pending application, Serial No. 799,705. The said cup is formed from a single blank 12 of approximately segmental shape, having two straight sides and one arc-shaped .or curved side. The said blank may be considered as being originally of semi-circular shape, and having one end cut off. 7

That portion of the cup between the line 13 and the base or diameter line of the blank indicated at 15 is then formed into conical shape, asshown in Fig. 4, with that portion between the line 13 and the short defining straight line 16 forms a flap engaging the outer face of the opposite end i under ordinary circumstances, but will notinterfere with the speedy removal of the same when desired.

1. A cup or dish of the character specified, formed from a blank of approximately circular form, said blank being creased from the center to-the periphery on two lines at an angle of 90 with respect to each other,

and having a strip removed at the periphery between the two lines and an are parallel with -the periphery, and having a third creasefrom the center of the strip to the center of the blank, that portion of the blank between the first-named crease lines being folded outwardly and doubled upon itself to form a conical receptacle and a radial flap, the free edge of the blank being bent outwardly in beaded form.

2. A cup or dish of the character specified, formed from a blank of approximately circular form, said blank being creased from the center to the periphery on two lines at a substantial angle with respect to each other, and having a strip removed at the periphery between the two lines and an are parallel with the periphery, and having a third crease from the center of the strip to the center of the blank, that portion of the blank between the first-named crease lines being folded outwardly and doubled upon itself to form a conical receptacle and a radial flap.

3. A cup or dish of the character specified, formed from a blank of approximately circular form, said blank being creased from the center to the periphery on two lines at a substantial angle with respect to each other, and having a strip removed at the periphery between the two lines, and an are parallel with the periphery.
